But in some rural areas where there are no phones, walls of buildings have been turned into diaries where contacts are written and kept for later use.
At Mempemehonasem , a rural community in the Ga West District of the Greater Accra Region, the walls of most houses there are adorned with phone numbers and names .
These are usually contacts of relatives or friends living in the city.
TV3’s Kwabena Adu Gyamfi found out that writing contacts on walls can only be done on the individual’s building and not on someone else’s edifice.
“I can save the contact in a book but the book can easily get missing but on the wall, it can never be wiped off” one resident told TV3.
But keeping contacts on walls certainly means there is no privacy and until mobile phones are introduced in rural communities, the walls of buildings will continue to serve an additional role as contact keepers.
